Following are a number of back-translations as well as a sample translation for translators of Amos 2:4:

• Kupsabiny: “God is saying,
  ‘The people of Judah sinned repeatedly.
  I will punish those people for sure
  because they despised my teachings
  and did not keep my wishes.
  Also their forefathers who worshipped worthless idols went astray.” (Source: Kupsabiny Back Translation)
• Newari: “This is what the LORD’s says,
  "The people of Judah have sinned again and again,
  I will surely punish them.
  They have rejected the Laws of the LORD,
  they have not heeded his ordinances.
  The gods which their forefathers followed,
  led them also on the wrong way.” (Source: Newari Back Translation)
• Hiligaynon: “This is what- the LORD -says concerning Juda : Because of the continuous sinning of those who-come-from-Juda, I will- surely/severely -punish them. For they rejected my laws and they did- not -obey my regulations. They were-led-astray by their serving the gods which their ancestors had- also -served.” (Source: Hiligaynon Back Translation)
• English: “Yahweh also said this:
  ‘I will also punish the people of Judah because of the many sins that they have committed;
  I will not change my mind about punishing them,
  because they have rejected what I taught them
  and they have not obeyed my commands.
  They have been deceived and persuaded to worship false gods,
  the same gods that their ancestors worshiped.” (Source: Translation for Translators)
